1994 Camaro rough oepration and reduced power


I have a 94, and mine ran rough until I had a new computer control chip put in. The dealer doesnt sell then anymore, so you would need to get a reconditioned one (is that the right word?) from an auto parts store. I had to get this done twice because the first one was bad so they swapped it out. There was one more thing the former owner did to fix a rough run situation, I will post it when I find the receipt. Also, it smoothed out even more when I changed out the motor mounts. WAY less vibration. I love to drive this car now!

Airscrew


Before you could adjust the mixture, make sure that the spark plug gaps, ignition timing and valve clearance are all OK.
- Start the engine and bring it at operating temperature.
- Adjust the throttle stop screw to bring it at the stable rpm.
- Turn in the idle mixture screw while observing the engine speed till the engine starts to stall. At this point turn out the idle mixture screw and keep on opening slowly till the engine acquire the most stable rpm. Finally adjust the throttle stop screw to obtain the desired idle speed.

Car hiccups and stalls


Although your temperature gauge may show that it works, some models have a second temperature sensor for the engine management system.
That second sensor provides info which sets curb idle and timing advance. The "Cold start" feature is a part of this. The hic-cup is something of a bucking symptom as the engine controls toggle between hot and cold run settings repeatedly as water temperature is not stable.
In the past, I found several 1984 engines having defective thermostats which are tied into "Step-up" solenoids for the curb idle. What happens is idle speed is suppose to drop when the engine is hot.
When someone adjusts the curb idle while the engine is on the "cold setting", the setting(rpm) will be too low once the engine has heated up and the part drops to a hot setting.
So to clearly define your problem, you have 2 stemming from the same defects. The "in motion" problem is caused by timing changes based on temperature and the "idle" problem is caused by improper adjustment of the curb idle solenoid because of unstable operating temperature.
What you want to do is change your thermostat. This will give you a stable temperature. Then let the engine heat up and you should notice a "click" and the engine should idle down. It may stall. Then turn the idle rpm up until the engine will not stall.
The hic-cups should disappear once the operating temp is reached. If you still have problems then look for the water temperature sensors before replacing expensive parts.

The fuel pump was changed,now it idles high.


The idle speed is controlled by an Engine Control Module (ECM).
It needs to be put on a computor to be checked.
The idle air valve provides the control for constant idle speed. In order to set the correct air valve opening to achieve constant idle speed, the fuel injection control unit uses information from the air mass meter, A/C switch, throttle valve switch and the ignition control unit (RPM signal) to regulate the output current to idle air valve. This means, there is alot of things that can make the idle speed go up or down...Hope this was some help to you??

I have a nissan axxes 1991 the idle is not stable and its bucking when driving and stalled a few times when i want to stop,gas filter ,catalitic converter,plugs wire ,air filter are new and i also changed...


Have a fuel pressure test done, that will show a weak fuel pump, or bad fuel pressue regulator, also have the throttle position sensor checked.
Could be the idle air control valve,
could be the fuel bypass valve.
Without checking and testing, it's hard to pin point the problem.
